We investigated coexisting autoantibodies in sera of 553 patients with a neurological presentation and one or more paraneoplastic neuronal nuclear or cytoplasmic autoantibodies: antineuronal nuclear autoantibody type 1 (ANNA-1), ANNA-2, ANNA-3; Purkinje cell cytoplasmic autoantibody type 1 (PCA-1), PCA-2; and CRMP-5-immunoglobulin G or amphiphysin-immunoglobulin G. Except for PCA-1, which occurred alone, 31% of sera had more than one of these autoantibodies. In addition, 25% of sera had neuronal calcium channel (P/Q-type or N-type), potassium channel, ganglionic acetylcholine receptor, muscle acetylcholine receptor, or striational anti-bodies. The autoantibody profiles observed in patients with paraneoplastic disorders imply the targeting of multiple onconeural antigens and predict the patient's neoplasm, but not a specific neurological syndrome.
